GAR COUPLING.

Application filed March 19, 1920. Serial N0. 367,185.

To all whom it may concern: v

Be it known that T, THOMAS l loronnrss,

a citizen of the United States of America,

and resident of Clinton, in the county of Vermilion and State of Indiana, have invented certain new and useful Improve ments in Car Couplings, of which the following is a specification.

This invention relates to more particularly to couplings employed for coupling adjacent cars of a train.

The primary object of the invention is to provide a device of this character having means to insure against the sections of the coupler becoming accidentally disengaged, when the same have been locked together.

With the foregoing and other objects in view, the'invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

Referring to the drawings- Figure 1 is a side elevation of a coupler constructed to accord with my invention.

Figure 2 is a plan view.

Figures 3 and 1 are plan views which illustrate the coupling members separated.

Figure 5 is a front elevation partly in section and 30 Figure 6 is a fragmentary vertical section illustrating the members of the coupling connected.

Referring to the drawings, the coupler includes two complemental members or drawheads 5 and 6 which are each provided with openings 7, for the reception of pins or bolts and with recesses which are intersected by the openings, and in such respect the members 5 and 6 are similar.

The member 5, is formed to provide an open ended recess 8 of rectangular formation which is adapted to receive the spaced jaws 9 of the complementary drawhead 6, and the side walls of the member or drawhead 5 have formed therethrough circular openings 10, for the reception of circular portions 11 carried by and rigidly attached to a yoke, the circular portions 11 being fixedly attached to a rectangular cross piece 12 and to the side members 13 of the yoke to maintain said yoke in swinging engagement with the drawhead or member 5.

The yoke which is maintained in swinging engagement with the drawhead 5, may 55 be considered as an integral structure when assembled, and comprises the circular bearcouplings, and

ings or connecting means for connecting the yoke with the member 5, the bearings being connected with the cross piece 12 and with p the side members 13 which overlie a portion of the sides of the member 5, the side members 13 having a. straight edge which extends to a depending portion 16, and the sides curve upward and are connected opposite the projecting portion by a. cross bar 14:, which may be centrally provided with an extension 15, having therein a recess or opening for the reception of one end of a bolt. The member 5 is provided with blocks or outward projecting portions 17 located on opposite sides thereof and positioned to maintain the yoke against movement beneath said member, and as shown by dotted lines on Fig. 1, the yoke may be positioned when in non-operative position so as to rest upon the upper surface of the member 5, and when in such position the cross piece 12 will be in parallel relation to the upper and lower walls of the member 5, so that the fixed or n0n-movable jaws 9 may pass beyond the cross piece.

The member or complementary drawhead 6 is exteriorly provided in its upper surface with a transverse recess 18 that is positioned to receive the cross bar 14 of the yoke, and it is provided with a bolt 23 which when projected engages or enters the recess or aperture formed in the head 15. The member or drawhead 6 is provided with blocks 19 which project therefrom and are positioned to be engaged by the projecting portions of the side pieces of the yoke, when the transverse bar 14 lies in the recess 18. The yoke which is in swinging engagement with the drawhead 5 when positioned to enage the drawhead 6 connects the drawheads and holds the same in fixed engagement the yoke being held in locked position by the bolt.

In order to hold the members 5 and 6 in alinement the member 6 has formed there with a forwardly projecting portion 20, the same being shaped to provide rigid jaws 9 that have inclined faces 21 and shoulders 22. The jaws 9, are so spaced as to admit between them the cross piece 12 when the yoke is in non-operative position, and when such yoke is in operative position the shoulders will be in line with end portions of the cross bar and such structure will serve as an emergency coupling in case of breakage of the yoke.

This "device though designatedkasn a car coupllngz may be used for other purpose, for instance as a coupling :tor connecting tractors to Wagons or agricultural or other machines.

I claim 1. A coupler comprising a. section having an openended recess, a yoke haying side pieces, a cross bar fixedly attached to the side the cross bar that intersects:the -recess in the l fi-rstzwmentionedsection, and a transverserecessin thecomplementary section in-Uwhich the -seco'nd crossbar iswadap-ted to be seated.

2. A' coupling comprising: a, section having :an openended" recess, and apertures through opposite side Walls of said =section, ayoke vin a-intained in swlnging engagement with said section= and= comprising side pieceswhich are'connected by cross bars, one of i the'icross bars intersecting the' openended recesscand the other 'cross bar" movable in the erect a circle, for HSG'Wltll :another section having. projecting-' members which are spaced to admit between them thecross bar that iinterseotsthe openended recess, a transverse recess for the reception of the other cross bar oiithe yoke, and projections -;-with yoke engage.
